A solid cylinder of mass $\displaystyle 50$ kg and radius $\displaystyle 0.5$ m is free to rotate about the horizontal axis. A massless string is wound round the cylinder with one end attached to it and other hanging freely. Tension in the string required to produce an angular acceleration of $\displaystyle 2$ revolutions $\displaystyle \mathrm{s}^{-2}$ is :
